Reordering Object Properties in JavaScript

I have an object att = {at0: 'bbb', at1: 'aaa', at2:'ccc'} and when using Object.keys(att) I have this order: 0: at0, 1:at1, 2: at2. I want re-order the object att in order to have 0:at1, 1:at0, 2:at2

To reorder the properties of an object in JavaScript, you can create a new object and assign the properties in the desired order. Here's how you can do it for your specific case:

let att = { at0: 'bbb', at1: 'aaa', at2: 'ccc' };

// Create a new object with the desired order
let reorderedAtt = {
    at1: att.at1, // first property
    at0: att.at0, // second property
    at2: att.at2  // third property
};

console.log(reorderedAtt);

After running this code, reorderedAtt will have the properties in the order you specified:

{
    at1: 'aaa',
    at0: 'bbb',
    at2: 'ccc'
}

Keep in mind that the order of properties in an object is generally based on the insertion order, but when you create a new object, you can control that order explicitly.
